Important note: Secret Clinical Strength Advanced Solid is for underarm use only. Consult with your doctor if you need antiperspirant protection anywhere else on your body. Apply at bedtime. It will work while you sleep to reduce excess perspiration. It will continue to protect you throughout your next day even if you bathe or shower the next morning. If you apply in the morning, you will still get strong wetness protection; however, for optimal performance apply at night. A light layer of Secret Clinical Strength Advanced Solid is recommended. Customize the protection that's right for your personal needs by adjusting the amount dispensed. The average dose is 2 clicks per underarm.
